GMTS0519 type Gold mining Trommel screen
— Gold mining Trommel screen Overview —
Gold mining equipment, also known as portable gold extraction equipment, is a type of machinery mainly used for sorting placer gold ore. As a mobile gold mining device, it can be fed manually or by a loader into the hopper. The materials are then screened by a trommel screen or a washing drum. Large-grained waste is discharged, while the remaining materials are further concentrated by a vibrating sluice box or a fixed sluice box.
Processing Capacity : Varies by model size; refer to the parameters for specific details.
Feed Size: 350 mm ~ 425 mm
Processed Materials: Placer gold ore, placer gold, diamonds, etc.
Application Field: Mainly used for the recovery of free gold from placer gold ore and vein ore,river placer gold, placer gold mines, tailings reprocessing, dry land/shallow water gold mining.

—Core Structure of Gold Mining Trommel Screen —
Main Body:
An inclined screening drum (composed of multi-section screen meshes for classification from fine to coarse). High manganese steel/stainless steel screen meshes are commonly used, and the drum body is made of carbon steel/stainless steel.
Drive System:
A motor plus a reducer (or chain) that drives the drum to rotate at a low speed (usually 10–20 rpm).
Water Supply System: Central direct flushing + side spraying to strip clay and sediment from the surface of gold particles.
Auxiliary Components:
Frame, feed hopper, discharge hopper, sealing cover, and comb-shaped screen cleaning mechanism (for anti-clogging).
—Core Advantages Gold Mining Trommel Screen—
Anti-clogging & High Efficiency:
Rolling scrubbing + water flushing solves the problem of screen clogging caused by wet and sticky materials. The screening efficiency can reach over 90%, which is superior to that of vibrating screens.
Flexible Mobility:
Usually integrated on a trailer chassis, operable by 1–2 people. No disassembly is required for relocation, and it can be used immediately upon arrival at the mining area (plug-and-play).
High Gold Recovery Rate:
Multi-stage screening + sufficient desliming fully expose gold particles. Combined with subsequent gold separation equipment, the gold recovery rate can reach over 90%.
Environmental Protection & Energy Saving:
Sealed design reduces dust emission; optional water circulation system can save 70% of water.
